A football (450 g) falls vertically from rest onto the ground from a height of 5.0 m. If the force that compresses the ball when it hits the ground is (100 N). What is the amount of compression of the ball? Draw explanatory diagram.

its lower due to the doppler effect.: apex

answer: the potential energy decreases from 379 j to 243 j

explanation:

for the law of conservation of energy, the total energy in a system must be conserved. the total energy of the system is given by the sum of kinetic (k) and potential (u) energy:

e = k + u

the total energy is e=675 j, and this does not change.

initially, the kinetic energy is k=296 j, so the potential energy is

at the end, the kinetic energy is k=432 j, so the potential energy is

so, we see that the potential energy has decreased from 379 j to 243 j.
